LUBItIcArfNe comiosmroi no Drawing. AppHcation'fled January 2a, 1921, Serial no, 440,75 Renewed October 29, 1925.

To all whom itmay concern:

'Be it known that I, IDA M: Cns'rnn, a citizenof the United States, residing at Bahway, in the county oi Union and Statelard and thoroughly blended. I then add i 6 of New J ersey," have invented certain new and useful Im rovements in Lubricating Composition, 0 which the following is a specification.

" This IIWGIltlQI]. is a novel lubricating com- '10 position applicable particularl'y for userin thos'e relations where a high penetrative quality requires to be combine d with alubricating effect which is more positive and permanent than is obtainable from oil or 16 grease films or the like, typical examples beiiig the lubrication of -automobilaspring leaves, the freeing of rust-bound surfaces such, as tire rims, nuts, etc. etc.

My novel composition comprises graphite.-

' 20 which has been reduced'to the colloidal state by theknown rocesses of deflocculation (see for examp e U. S; patentsjto E. G. Acheson, Nos. 844,989, 911,358, 966,636,

"28' big penetrating liquid vehicle capable of carrymgf'thd defloc'culated graphite in sus-o coal .tar oil,-,kerosene, lardand red oii.

pension and preferably consisting vof amixi :ture of mineral and animal oilsor,grea s es. -Following*is a specific example in accord- 80 ahce with my invention, it being clearly understoi'gd that the invention is not restricted to the precise-grades or qualities of mate tions-spec ified. i r SI" A proximately 1 pint 0f ,defloccg lated grap 'to inthe form of the commerc al o (paste is with 2 quarts of lard and 4 -quarts of the productcommercially known rials mentioned or to thepartieulargprgpor and .a substantially non volatile, but

as red oil or red engine oil, a crude oil dis tillate of lubricating grade. The mixture40 is warmed to about the melting point of the with stirring 8 quartsof coal tar oil, of the grade known as special heavy (Barrett) and 6 quarts of, kerosene. This coal tar oil v 'is also widely known as .creosote oil.

The above components blend to a homoge'neous; mobile, highly penetrative' c'omposition whi'ch when applied -to, contacting or 'rust bound surfaces, as springleaves, etc., 60

penetrates the interstices and forms therein a graphitic deposit or surface which not only prevents squeaking but -acts as 'a suh-' stantial preventive ofrust.
